Oil seals are generally constructed from materials that can withstand the specific chemical properties of the lubricant they are sealing. Common materials include rubber, silicone, and various elastomers. The design of an oil seal often incorporates a lip that rolls against a shaft or surface, creating a dynamic seal that can accommodate movement while maintaining its sealing capabilities.

Another important function of a dust seal is to prevent leakage of hydraulic fluid. If dust and dirt particles are allowed to enter the cylinder, they can create small gaps and openings that allow fluid to escape

hydraulic cylinder dust seal. This can result in a loss of pressure and reduced performance of the hydraulic system. Dust seals help maintain the integrity of the cylinder by sealing off any potential entry points for contaminants, preventing leaks and ensuring the proper functioning of the system.

The percentage of an oil seal refers to its ability to effectively prevent leakage. A higher percentage indicates a better sealing capacity, with 100% being the ideal value. However, in reality, achieving a perfect seal is often challenging. Therefore, oil seals with percentages ranging from 25% to 35% are commonly used in applications where a high level of sealing performance is required.
